The message part performs a function for transmitting an MAC protocol data unit (hereinafter, abbreviated to PDU) transferred from the MAC to the physical channel. - When the MAC of the UE instructs a PRACH transmission to the physical layer of the UE, the physical layer of the UE first selects one access slot and one signature, and transmits the preamble on the PRACH to an uplink. The preamble is transmitted within an access slot duration having a length of 1.33 ms, and one signature is selected from 16 signatures within a first certain length of the access slot and is transmitted. When the UE transmits the preamble, the Node B transmits a response signal through an acquisition indicator channel (AICH) which is a downlink physical channel. The AICH, in response to the preamble, transmits the signature which was selected by the preamble within the first certain length of the access slot corresponding to the access slot for transmitting the preamble. At this time, the Node B transmits an acknowledge (ACK) response or a non-acknowledge (NACK) response to the UE through the signature transmitted by the AICH.
- When the UE receives the ACK response, the UE transmits a message part having a length of 10 ms or 20 ms using an orthogonal variable spreading factor (OVSF) corresponding to the transmitted signature.
- When the UE receives the NACK response, the MAC of the UE instructs a PRACH retransmission to the physical layer of the UE after a certain time period. In contrast, if the UE does not receive the AICH corresponding to the transmitted preamble, the UE transmits a new preamble with power higher than that of the previous preamble, after a predetermined access slot.
-
FIG. 4 is a view showing an exemplary structure of an AICH which is a conventional downlink physical channel. - The AICH, which is the downlink physical channel, transmits 16 symbol signatures (Si, i=0 ... 15) for the access slot having a length of 5120 chips. Here, the UE may select any arbitrary signature (Si) from S0 signature to S15 signature, and then transmits the selected signature during the first 4096 chips length. The remaining 1024 chips length is set as a transmission power off period during which no symbol is transmitted. Also, as similar to
FIG. 4 , the preamble part of the PRACH, which is the uplink physical channel, transmits 16 symbol signatures (Si, i=0 ... 15) during the first 4096 chips length. - However, in the conventional RACH transmission, since the downlink message, which is transmitted in response to the uplink RACH message transmission, is transmitted with high power so as to be received even in a cell boundary, a radio resource was inefficiently used.
- In
WO 2005/122616 A1 , it is disclosed that a communication terminal device for eliminating collision of access request signals simultaneously transmitted from communication terminal devices in a local cell, preventing generation of interference signal in another cell adjacent to the local cell, and improving the throughput in the local cell, and a base station device for controlling the transmission power of the access permission signal so as to prevent generation of an interference signal in another cell adjacent to the local cell. - Accordingly, the present invention is directed to a method for transmitting a random access channel message and a response message, and a mobile communication terminal that substantially obviate one or more problems due to limitations and disadvantages of the related art.

-
FIG. 5 is a view showing an example of amobile communication terminal 510 according to the present invention. - A downlink
channel measurement unit 511 measures the quality of a downlink channel from a downlink signal of aNode B 520 and generates quality measurement information of the downlink channel. - A
message transmission unit 512 includes the quality measurement information in a random access message, that is, a RACH message, and transmits the RACH message to theNode B 520 through an uplink signal. The embodiment may vary depending on in which portion of the RACH message the quality measurement information is included. That is, in themobile communication terminal 510 according to one embodiment of the present invention, themessage transmission unit 512 includes the quality measurement information in a header of a second layer L2 of the RACH message.

The downlinkchannel measurement unit 511 and themessage transmission unit 512 may be implemented by a single chip for implementing all logics. -
FIG. 6 is a view showing a random access process according to an embodiment of the present invention. - In one embodiment of the present invention, in order to efficiently use a radio resource, a radio user equipment (UE) includes the quality measurement information of the downlink channel in the header of the second layer L2 of the RACH message transmitted to an uplink. A radio network controls transmission power of a response message for the RACH message using the quality measurement information included in the header of the second layer L2 and transmits the response message to the UE.
- In another embodiment of the present invention, in order to efficiently use a radio resource, the UE includes the quality measurement information of the downlink channel in the payload next to the header of the second layer L2 of the RACH message transmitted to an uplink. The radio network controls transmission power of a response message for the RACH message using the quality measurement information included in the payload and transmits the response message to the UE. In this case, the radio UE may include the quality measurement information in a L2-PDU in a piggybacking fashion and transmit the RACH message to the radio network.
- This embodiment will be described with reference to
FIG. 6 as follow. - The
UE 510 can transmit the RACH message after a RACH preamble transmission process and a process of responding to the RACH preamble, as shown inFIG. 6 . - Accordingly, the
UE 510 first transmits the preamble of the RACH to the Node B 520 (610). - Next, when the preamble is accurately received, the
Node B 520 transmits an ACK response for the RACH preamble to the UE 510 (620). In contrast, when the preamble is not received or is inaccurately received, theNode B 520 transmits a NACK response for the RACH preamble to the UE 510 (620). - Next, the
UE 510 transmits the quality measurement information of the downlink channel of theNode B 520, for example, the RACH message including a channel quality indication (CQI), to the Node B 520 (630). At this time, the RACH message may include at least one L2-PDU. If the L2-PDU includes the quality measurement information, the header of the L2-PDU, that is, the L2 header, can notify whether the quality measurement information is included in the L2 header or the L2-PDU including the header of the L2. For example, the L2 header may be a MAC header configuring the MAC PDU. In more detail, information indicating whether or not the CQI is included in the MAC PDU may be stored in a target channel type field (TCTF) of the MAC header. - The MAC PDU may include a RRC message transmitted to a common control channel (CCCH), a dedicated control channel (DCCH) or a dedicated traffic channel (DTCH), all of which are the logical channels.
- When the UE is turned on and then first accesses a new cell, the UE establishes downlink synchronization and receives system information of the cell to be accessed. After the system information is received, the UE transmits an access request message for RRC connection. However, since the UE does not establish time synchronization with a current network and a uplink radio resource is not ensured, the RACH may be used. That is, the UE requests the radio resource for connection request message transmission to the network using the RACH. The Node B which receives the request for the radio resource allocates a proper radio resource to the UE. Then, the UE can transmit a RRC connection request message to the network through the radio resource.
- In a state in which the UE is RRC-connected with the network, the UE which is in the RRC connected mode may use the RACH. In this case, the UE receives the radio resource allocated according to radio resource scheduling of the network and transmits data to the network through the allocated radio resource. However, if data to be transmitted is no longer left in the buffer of the UE, the network no longer allocates the uplink radio resource to the UE. This is because the allocation of the uplink radio resource to the UE which does not have data to be transmitted is inefficient. If new data occurs in the buffer of the UE which does not have the radio resource, the UE may use the RACH because the uplink radio resource is not allocated to the UE. That is, the UE may make a request for the radio resource necessary for transmission of data to the network using the RACH.
- That is, some RRC messages such as a RRC connection request message, a cell update message and a URA update message may be also transmitted through the RACH. At this time, the CCCH, the DCCH and the DTCH, all of which are the logical channels, may be mapped to the RACH which is the transport channel.
- The quality measurement information of the downlink channel may be included in the L2 header, for example, the MAC header, or may be included in a front portion of a MAC payload or a rear portion of the MAC payload next to the L2 header in a piggybacking fashion.
- Next, the
Node B 520 performs adaptive modulation control (AMC) or power control using the quality measurement information of the downlink channel (640). At this time, the second layer, that is, the MAC layer, of theNode B 520 receives the MAC PDU of the RACH message, checks the MAC header, and checks whether the quality measurement information of the downlink channel is included in the MAC PDU. At this time, if the MAC header notifies that the quality measurement information of the downlink channel is not included, theNode B 520 does not associate the control of the transmission power with the quality measurement information. - Finally, the
Node B 520 transmits a RACH response message to theUE 510 using the transmission power controlled according to the quality measurement information of the downlink channel (650). - The
UE 510 may include L3 information as well as L2 information in the RACH message, which is transmitted to the uplink, and include the quality measurement information. of the downlink channel in the L2 information. At this time, the L3 information may be the RRC message. In addition, the L2 information may notify theNode B 520 that the quality measurement information is included in the L2 information. In particular, the L2 information may be MAC control information which is included in the MAC header or the MAC PDU in the piggybacking fashion, and may be MAC control information included in the payload of the MAC PDU. - In this
step 650, three following cases may be realized depending on whether or not the L3 information is included or whether or not the quality measurement information is included in the L2 information. - First, if upper layer information is included in the MAC PDU and the MAC header notifies that the quality measurement information of the downlink channel is included, the
Node B 520 removes the quality measurement information from the MAC PDU and reconfigures the MAC PDU. TheNode B 520 sends the reconfigured MAC PDU to the MAC of the RNC. In addition, theNode B 520 transmits a response message for the RACH message received from theUE 510 to theUE 510. - Second, if the upper layer information is not included in the MAC PDU and the MAC header notifies that the quality measurement information of the downlink channel is included, the
Node B 520 does not send the MAC PDU to the RNC. In this case, theNode B 520 only transmits the response message for the RACH message to theUE 510. At this time, the response message includes the ACK response for notifying that the RACH message is successfully received and the NACK response for notifying that the RACH message is not successfully received. The response message includes information indicating the RACH preamble or information indicating the RACH message. At this time, the indicating information included in the response message may be code information for transmission of the message or the signature of the preamble. - Third, if the MAC header does not notify that the quality measurement information of the downlink channel is included, the
Node B 520 only sends the MAC PDU to the MAC of the RNC and transmits the response message to theUE 510. - The RACH response message of the
Node B 520 may be transmitted through the L2-PDU, for example, the MAC PDU or may be transmitted through a physical layer control signal. If the response message is transmitted through the MAC PDU, the header of the MAC PDU including the response message notifies theUE 510 that the response message is included in the MAC PDU. In particular, the UE may be notified that the response message is included in the MAC PDU, using the TCTF of the header of the MAC PDU. -
FIG. 7 is a view showing an example of the random access process shown inFIG. 6 . - After the transmission (AP) of the RACH preamble and the response (AICH) of the RACH preamble, the
UE 510 measures the downlink channel of theNode B 520, includes the quality measurement information in the MAC payload or the MAC header of the MAC PDU, and transmits the RACH message to the uplink. - The response message MSG-ACK/NACK of the
Node B 520 for the RACH message is the ACK signal for notifying that the RACH message is successfully received or the NACK signal for notifying that the RACH message is not successfully received. - Meanwhile, when the
UE 510 receives the MAC PDU from theNode B 520 and checks that the response message MSG-ACK/NACK is included in the MAC PDU through the header of the MAC PDU, theUE 520 can retransmit the RACH message to theNode B 520 according to the response message MSG-ACK/NACK. In particular, theUE 510 does not retransmit the RACH message if the response message MSG-ACK/NACK received from theNode B 520 is the ACK response and retransmits the RACH message to theNode B 520 if the response message is the NACK response. -
FIG. 8 is a view showing an example of the MAC PDU configured according to an embodiment of the present invention. - In
FIG. 8 , the TCTF is included in the MAC header. The TCTF may notify whether or not the quality measurement information, that is, the CQI, is included in the MAC PDU, as described above. The MAC PDU may further include other information such as a UE-Id, a C/T, a MAC service data unit (SDU). - In the present invention, the mobile communication terminal includes the quality measurement information of the downlink channel in the L2 header or payload of the RACH message transmitted to the uplink, and the radio network controls the transmission power of the response message for the RACH message using the quality measurement information included in the L2 header or payload and transmits the response message to the UE. Accordingly, it is possible to efficiently use the radio resource.

Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
